Case of the Month 3Diagnosis
Unilateral Pulmonary Edema secondary to severe mitral
valve regurgitationDifferential Diagnosis - Pulmonary infection- Alveolar hemorrhage- Carcinomatous lymphangitis- Aspiration pneumonitis
Case of the Month 3Discussion
Cardiogenic unilateral pulmonary edema (UPE) is a rare entity, frequently leading to initial misdiagnosis
UPE represents about 2.1% of cardiogenic pulmonary edema
UPE is always associated with severe mitral regurgitation
UPE is related to an independent increased risk of mortality and should be promptly recognized to avoid delays in treatment
Case of the Month 3Discussion
Left ventricle, mitral valve, left atrium, right superior pulmonary vein, and the RUL are aligned along the path expected for a regurgitant jet caused by mitral insufficiency, with a resulting increase in hydrostatic pressure in the right superior pulmonary vein
Asymmetric pulmonary edema concentrated in the right upper lobe is typically associated with mitral regurgitation resulting from a flail posterior leaflet, which can be caused by rupture of the chordae tendineae or papillary muscle
Case of the Month 3Discussion
CHEST RADIOGRAPHY Loss of definition of segmental and subsegmental
vessels Enlargement of peribronchovascular spaces and
peribronchial cuffing Kerley lines Areas of increased opacity Pleural effusion All findings are more conspicuous on the right
HIGH-RESOLUTION CT Ground-glass opacity Smooth interlobular septal thickening Peribronchovascular interstitial thickening Increased vascular diameter Pleural effusion All findings are more conspicuous in the RUL
